Specification of Letters Patent. Pateflted.N V 1912,

Application filed February 14,1912. Serial No. 677,498.

' Beit known that I, WILLIAM J OHN MAGEE, a citizen of the United States, residing at New Orleans, in the parish of Orleans and State ofLouisiana, have inventedcer'tain new and useful Improvements in- Switch- I boards; and I do hereby declare the follow- T 'plates to the switch terminals; thereby proing to be a full, clear, and exact description the lnvention', such as will enable others skilled in the art to which it appertains to make and use the same. w

' My invention relates to improvements in swltch boards, and it'consists 1n the con, structions, combinations, and arrangements herein described and claimed.

An object of my invention is to provide an lmproved switch board having sections of insulated copper secured together to constitute continuous, insulated bus bars, which are electrically connected by flat cross viding a. simple and inexpensive construcftion which is efiectively protected from danger of cross circuits, and in which the bus bars and switches can be more compactly and conveniently assembled than has been possible in previous constructions.

a part of this application, and in which similar reference symbols indicate corresponding parts in the several views :-Figtion on the line 2-2 of Fig. 1; Fig. 3 is an enlarged, detail, axial section, through a pair of connected bus barsections and the panel section; Fig. 4 is a front elevation of a main panel section provided with a through-feed, two-wire main; and Flg. 5

is a section on the line 55 of Fig. 4.

Referring to the drawings, 1 indicates duplicate sections of insulated copper secured together by pins 2 to constitute continuous, insulated bus bars; the pins 2 being preferably heated and inserted in previously tinned bores 3 in the ends of said sections.

' The sections 1 are spaced from the panel by integral supporting legs 5, and flat metal plates 6 and 7 are clamped between said supporting legs and the panel by screws 8, to provide electrical connections-between the bus bars and the switch terminals 9 and 10.

Figs. 4 and 5 illustrate my invention applied to a main panel section provided with a through-feed, two-wire main, in which the sectional bus bars 16 are provided at both ends with the main-line switches. v

I have illustrated panel sections equipped Y with both knife switches 11 and snap switches 12, and having both inclosed fuses 1'3 and plug fuses l-l in the two wire branches, but my invention is equally adapted for use with any usual types of two-wire or threevenient operation, with a minimum danger ofcross circuits and accidents. In the accompanying drawings forming I claim 1. In a switch board, an insulated bus bar comprising a series of abutting sections of bores and with offset legs for spacing said sections from the board, and pins secured within such boresfor fastening the ends of said abutting sections together. Y

2. In a switchboard, an insulated bus bar comprising a series of abutting sections of insulated wire formed with axial end bores and with offset legs toward one end for spacing said sections from the board, pins secured Within such bores for fastening the'ends of said abutting sections tobetween said legs and switch board. .7

In testimony whereof, I aflix my signa ture, presence of two witnesses.
